Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a grip fixing device for fixing a hollow snap-in type grip formed from a sheet metal to a container, the grip fixing device being fixed to the container and having a locking notch. When the grip is pressed into the holding web, a spring fixed to the grip engages with the locking notch, so that the grip is pressed against the container wall only by the spring force and held. Concerning things that have become popular.

The grip fastening device known from DE 25 01 404 serves for fastening a hollow grip with a spring fastened to the grip to a holding web fastened to a container. This known side grip with two grip legs is indeed held against the container by means of a spring, but this spring must at the same time also absorb lateral guiding forces. However, since no guide surfaces are provided in this known case, the acceptance of lateral guide forces by the springs can only be achieved very poorly. Furthermore, it is also not possible to arrange the holding webs fixed to the container at such a precise distance that they act as lateral guides for the grips. This is due to the relatively large tolerances that occur in the manufacture of the snap-on grip and in the fixing of the retaining web on the container. In order to avoid problems during this fixing, metal grips of this type are firmly connected to the container before enameling. However, this also presents its own problems if, after enameling, certain areas of the container are further electroplated. The danger that arises in this case is that the acid penetrates into the hollow grip and does not flow out of the grip even after the electroplating process, and that this acid residue can cause damage due to its long duration of action. be.

In plastic grips, corresponding guide surfaces can be integrally molded onto the grip, so that the problem of lateral guidance of the grip along the holding web does not arise. However, grips of this type have the disadvantage that they have poor heat resistance and cannot be used in the oven, and they have insufficient long-lasting strength and are susceptible to damage during use in washing machines.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve the grip fixing device of the type mentioned at the outset, so that even when side grips are later fixed, the grips can be permanently fixed to the container without any play, and which are simple in construction and inexpensive to manufacture. To provide a grip fixing device which is inexpensive and easy to attach to a side grip and a container. Another object of the invention is to design the retaining web for this grip fastening device in such a way that it can be used for both right-hand and left-hand grip fastening devices.

In order to solve the above problems, the configuration of the present invention includes:
Inserted into the hollow metal grip is an integrally formed guide and spring element for receiving the retaining web, which guide and spring element forms a guiding surface for the retaining web and a locking recess in the retaining web. and one or more spring tongues cooperating with the spring tongue.

According to an advantageous embodiment of the invention, the guide-spring element consists of a U-shaped profile which is fixed at the back to the inner wall of the metal grip, one or both spring legs of which It has a slit over part of its length, and the free end of the spring leg is deformed into a V-shape.

A hollow metal grip of the type mentioned at the outset is preferably formed from a sheet metal, which sheet metal forms an abutment on one side of the grip. It is advantageous if the back of the U-shaped profile is welded to this abutment point in such a way that it overlaps the abutment point and that during welding the ends of the metal sheets are fixed to one another. If welded in this way, no additional working steps are necessary for mounting the guide-spring element according to the invention. In this case, the shape and height of the retaining web are adapted to the guide-spring element in such a way that forces acting on the grip perpendicular to the container wall are transmitted directly from the guide-spring element to the retaining web. A spring integrally integrated in the guide element, which is V-shaped and cooperates with the locking recess in the retaining web in the inserted state, presses the grip continuously and without play towards the container wall, so that the grip Under normal loads, it is rigidly connected to the container wall. However, due to the inclined shape of the V-shaped spring ridge, the grip can be pulled away from the container again without damaging the container or the retaining web by using a relatively high force, thereby making it possible to replace the grip. becomes possible.

The retaining web has an approximately rectangular shape in plan view. According to an advantageous embodiment of the invention, the retaining web is designed symmetrically with respect to its two long sides, with the plane of symmetry extending through the center of both short sides. In this case, the short side of the side that is fixed to the container, such as a deep pot, is formed in a V shape, and the tip of the V shape is located on the symmetrical plane, and the angle of this V shape matches the roundness of the container wall. It is advantageous if they match. Also advantageously, the angle of this V is adapted to the roundness of a medium container size. In this way, it is possible to attach the holding web to both large and small containers without having to tilt the holding web to be welded too far from the target direction. .

Next, embodiments of the present invention will be described with reference to the drawings.

In the embodiment shown, the container 1 has two retaining webs 2.
are included, but only one of them is shown in the drawing. The retaining web 2 consists of a closed sheet metal strip that is approximately rectangular in plan view;
The side 3 of the retaining web 2 facing away from the container wall 1 is somewhat narrower than the side 4 welded to the container wall 1. The height of the holding web 2 can be seen from FIG.
The narrow side 3 of the holding web 2 has notches 5 on both sides, the two notches 5 each forming a locking notch. A hollow metal grip 6 is fixed to the holding web 2.
consists of a thin plate 7 which forms a continuous butt point 9 on the inside 8.

The hollow metal grip 6 has a U-shaped formation 10.
However, the back part 11 of the U-shaped body 10 is welded so as to overlap the inner wall of the metal grip 6.
The welding points for fixing the U-shaped body 10 to the hollow metal grip 6 are set so that the welding points are located on both sides of the butt point 9. With this configuration, the shape of the metal grip 6 is stabilized at the same time. As best seen in FIG. 1, the two legs 12, 13 have a slit 14 over part of their length;
As a result, the parts of the legs 12, 13 opposite the back 11 form springs 15, 16, respectively.
Both springs 15, 16 are formed in a V-shape, thereby forming a rising slope 18 and a descending slope 17 (see FIGS. 2 to 4).

The height of the holding web 2 is equal to the height of the leg 1 of the U-shaped feature 10.
2.13, so that the metal grip 6 can be fixed parallel to the container wall 1.
The holding web 2 is also laterally dimensioned in such a way that it contacts the inside of the back 11 of the U-forming 10 on the one hand and the inner wall of the metal grip 6 on the other hand, so that the metal grip against the container wall 1 is Fixation in the lateral direction of 6 is guaranteed. As a result, all forces acting out of right angles to the container wall 1 are transmitted directly from the metal grip 6 to the holding web 2.

When the guide-spring element, which is formed as a U-shaped profile 10, is pressed onto the holding web 2, first of all the rising bevels 18 of the springs 15, 16 come into contact with the holding web 2, so that both springs 15 , 16 are deflected. When the ridges 19 of the springs 15, 16 pass over the narrow side 3 of the retaining web 2, both springs 15, 1
6 is again somewhat relaxed, i.e. in accordance with the shape of the descending slope 17, so that the metal grip 6 has a spring 15,
16, it is held against the container wall 1 under constant play load.

The U-shaped feature 10 not only forms a spring for fixing the metal grip 6 to the container wall 1, but also provides a spring for the metal grip 6, i.e. for forces acting approximately parallel to the container wall 1. It also serves as a guide and a holding function. In addition, by fixing the U-shaped forming body 10 inside the metal grip 6, the shape of the metal grip 6 formed from the formed sheet metal is fixed. In this way, only the necessary welding in any case at the butt points 9 of the metal grips 6 is performed. The guide-spring element according to the invention is distinguished by its extremely simple construction, so that it is possible to attach the metal grip 6 to the container wall 1 continuously and without any play at a later time without requiring a small manufacturing outlay. It becomes possible to fix it.

In a further embodiment of the metal grip 6 shown in FIG. 5, in contrast to the embodiment of FIG. It is fixed to a protrusion 20 fixed to the metal grip 6.
Incidentally, the push-in type and the grip holding type by the grip fixing device are similar to those described for the embodiments in FIGS. 1 to 4.

The retaining web 21, which is shown in a further embodiment in FIG. is formed in a V shape.
A plane of symmetry 23 extends through the center of each short side 22,24. The V-shaped angle of the short side 22 allows the retaining web 21 to be fixed to the container wall 1 on the short side 22.
are selected such that they are correctly oriented with respect to the container wall 1, so that the desired contact of the holding web 21 on the metal grip 6 and the U-formation 10 takes place in the manner described.

In FIG. 6, on the right side, a retaining web 21 of the same shape is shown in the form of fixation on the container wall 1; however, this retaining web 21 on the short side
2 is welded to the container wall 1 on the other side. This right-hand retaining web 21, like the left-hand retaining web 21, is oriented in such a way that the contact between the metal grip 6 and the U-formation 10 is maintained in the desired manner. Due to the special design of the holding webs, it is therefore possible to use just one holding web for both grip sides, which greatly simplifies stock management. In order to secure the holding web 21 to the container wall 1, the holding web 21 is
A welding protrusion 25 is provided in the well-known manner.
